You people have been playing WoT too long.
Wanting 152mm derpzilla guns, 107mm guns that were never used and 85mm guns that probably couldn't fit into the original turret.
Now if you ask me i'd love to have this but why would HTC put it in the game? Nobody uses these early-war tanks and everyone (almost) plays the LWA.
You spent 1 minute reading wikipedia and think you know everything? Bad news - the 85mm gun was fitted its called the KV-85, it was a stop gap tank before other tanks could come into action to combat the Tiger and Panther, problem is the Russians knew Germany could only field so many of them, problem was they were not going to produce a tank entirely to combat it, Actually they were, but the IS-1 was pretty much canceled at this point. T-34(85) and Kv-1 were just variants designed in the every changing adaptions of tanks, just as the Panzer 4 went from a Breakthrough tank to a main battle tank. Early war the Panzer 3 and 4 could not even scratch a dent in the KV-1 or T-34. However as tactics grew, so did tank designs. The KV-2 was not a main battle tank, it was a breakthrough tank which the Russians improved on later in the war, things like the SU-122, ISU-122, SU-152, and ISU-152, to add that the KV-1 was actually used as a hybrid for the IS-1, however an interesting thing happened - the Russians producted enough Su-85's and Su-100's to combat Tigers/Panthers, that the JS-1 was found to not be needed, also its 85mm gun was not enough to be a breakthrough tank, refitted as the JS-2 it carried a 122mm gun.
The JS-2 could of been fitted with the 100mm BS-3 100 mm gun, which would of made the JS-2 a pure tank killer of Panthers/Tigers, however it wasn't simply needed as the Germans couldn't produce enough of either that the russians needed a tank killer.
Why don't anyone use early war tanks? actually some do, a Panzer F(L-43) is a pretty awesome perk farmer, if more tanks were added a large ENY based GV system could be made, however we have limited vehicles in Aces high this is why you don't see many EW tanks running around.
However the Midwar Panzer H is the most used tank every tour period.
